My mom and dad are 10 years apart but they did not meet untill mom was in her 20's. So large age differences don't bother me that much. Andy is at least 16 since he is alowed to drive a delivery bike which looks like a moped it can probably do at least 30 mph because they would probably need to deliver thing quickly so he would have to have a Class M2 license at least. So long as they don't do anything jail worthy untill Andys 18 I think their current relationship is perfect. Keep up the good work.
